The following will describe production examples for compound [2] as an intermediate compound for the production of the present compounds.

INTERMEDIATE PRODUCTION EXAMPLE 1

To a mixed solution of 121 g of sodium carbonate and 400 ml of water was added dropwise 77.1 g of 1,1-dibromo-3,3,3-trifluoroacetone at such a rate that the temperature of the reaction mixture became not higher than 55° C. After completion of the dropwise addition, the mixture was stirred at room temperature for 30 minutes, followed by adding 500 ml of water and then 40 g of 2-amino-2-(2,4-difluorophenyl)acetamide, and the reaction was allowed to proceed at 60° C. for 2 hours. After completion of the reaction, the reaction mixture was cooled to 10° C. or lower, made acidic by adding 80 ml of concentrated hydrochloric acid at the same temperature, and extracted with ethyl acetate. The organic layer was washed with water and then saturated sodium chloride solution, dried with anhydrous magnesium sulfate, and concentrated. The residue was subjected to silica gel column chromatography (eluent, hexane/ethyl acetate=4:1), which afforded 23.3 g (yield, 39%) of the desired compound, 3-(2,4-difluorophenyl)-6-trifluoromethyl-2-oxo-1,2-dihydropyrazine (compound 1-1004; m.p., 178.9° C.). The continued elution with the above solvent system gave 13.2 g of the configurational isomer, 3-(2,4-difluorophenyl)-5-trifluoromethyl-2-oxo-1,2-dihydropyrazine (m.p., 164.6° C.).

INTERMEDIATE PRODUCTION EXAMPLE 2

To a mixed solution of 17.2 g of sodium carbonate and 61 ml of water was added dropwise 10.9 g of 1,1-dibromo-3,3,3-trifluoroacetone at such a rate that the temperature of the reaction mixture became not higher than 55° C.

The following test examples will demonstrate that the present compounds are useful as active ingredients of herbicides. The present compounds are designated by their compound numbers shown in Tables 1 to 5.

The herbicidal activity was evaluated at 6 levels with indices of 0 to 5, i.e., designated by the numeral "0", "1", "2", "3", "4" or "5", wherein "0" means that there was no or little difference in the degree of germination or growth between the treated and the untreated test plants at the time of examination, and "5" means that the test plants died complete or their germination or growth was completely inhibited. The herbicidal activity is excellent when rated at "4" or "5" but insufficient when rated at "3" or lower.

TEST EXAMPLE 1

Foliar Treatment on Upland Fields

Cylindrical plastic pots of 10 cm in diameter and 10 cm in depth were filled with soil, in which the seeds of velvetleaf (Abutilon theophrasti) and ivyleaf morningglory (Ipomoea hederacea) were sowed, and the test plants were grown in a greenhouse for 15 days. Each of the test compounds listed below was formulated into an emulsifiable concentrate according to Formulation Example 2, which was diluted with water containing a spreading agent to a prescribed concentration. The dilution was uniformly sprayed over the foliage of the test plants with a sprayer at a volume of 1000 liters per hectare. After the application, the test plants were grown in the greenhouse for 19 days, and the herbicidal activity was examined. The results are shown in Table 9.

TEST EXAMPLE 3

Flooding Treatment on Paddy Fields

Cylindrical plastic pots of 9 cm in diameter and 11 cm in depth were filled with soil, in which the seeds of barnyardgrass (Echinochloa oryzicola) were sowed. These pots were flooded to form a paddy field, and the test plants were grown in a greenhouse for 7 days. Each of the test compounds listed below was formulated into an emulsifiable concentrate according to Formulation Example 2, which was diluted with water to a prescribed concentration. The dilution was applied to the water surface in the pots at a volume of 50 liters per are. After the application, the test plants were grown in the greenhouse for 19 days, and the herbicidal activity was examined. The results are shown in Table 11.
